Handsome, but... Robert Downey Jr.

"The key with the guys is to keep it classic. Any time anybody does something nutty, à la Mickey Rourke last year, it's just like, 'Oh my god, what are you wearing?' You have to keep it really simple. ... Robert Downey Jr.'s like the best actor ever, but he probably needs a better stylist. His bow tie was big and blue and kind of Ringling Brothers–esque, which makes me not happy."
